BL – Brushless motor.

CA (Abbreviation for “Cyanoacrylate”) – An instant type glue that is available in various viscosities (Thin, Medium, Thick, and Gel). These glues are ideal for the assembly of wood and plastic boat materials. Note: Most CA glues will attack Styrofoam.

CG (”Center of Gravity”) – For modeling purposes, this is usually considered — the point at which the boat balances bow to stern. This point is critical in regards to how the boat rides in the water. A stern-heavy boat will be very fast but generally very unstable and susceptible to blow-overs. If the boat is bow heavy, it will tend to track better and be slower. The rule of thumb for CG placement: Monos at 28 to 30% of the hull length measured from the transom. Catamarans at 28 to 30% same as monos. Hydroplanes at 1 to 3 inches measured from the sponsons transom. Typical starting point CG on a hydro would be at the trailing edge of the skid fin.
